SUNPOWER CORPORATION Document #524734 Rev G <br />SPAN TABLES, INVISIMOUNT Template FILE-074910, Ed. 2 <br /> <br /> <br />Document #524734 Rev G, Vol. 2 3 SunPower Proprietary <br /> <br />M <br />x The following equations reflect ASCE-prescribed calculations, with values specific to InvisiMount <br />included where possible. <br />x Note that some conservative assumptions have been made and, in some cases, the resulting <br />values may be more conservative than a site-specific iteration of the ASCE-based calculations. <br />x The below equations are applicable only to modules with an area equal to or greater than 19.5 <br />ft^2. <br />x See below glossary for definitions of all referenced variables. <br />x ASCE 7 §2.3 defines load combination equations for LRFD, which generate design load pressures. <br />The controlling equations which define the design load on the module are: <br />o =.+. <br />o =.+.+. <br />.+.+. <br /> <br />x The process for solving for these equations is as follows: <br />o Identify site-specific inputs: <br />ƒ =[ ] <br />ƒ =[ / / ] <br />ƒ =[ ] ℎ <br />ƒ =[ ] <br />ƒ =[ ] <br />ƒ =[ 1 / 2 / 3 ] <br />o Select the following coefficients from the below Look-up Tables: <br />ƒ =[ ] <br />ƒ =[ ] <br />ƒ =[ ] <br />ƒ ,=[ ] <br />ƒ ,=[ ] <br />o Use the following equations to establish wind and snow loads: <br />ƒ The minimum allowable value for & is 16 psf. <br />ƒ Wind, Uplift: =.∗ ∗ , <br />ƒ Wind, Downforce: =. ∗ ∗ ∗ , <br />ƒ Snow: =,∗ () <br />If ≥15°, ,= 0.84 ∗ ∗ <br />If < 15° < 20 , ,= <br />If < 15° > 20 , ,=20 <br />0.84 ∗ ∗ <br />o Add the resulting load pressures in the load combination equations (dead load is <br />provided): <br />ƒ =. +. <br />ƒ =. +.+. <br />. +.+. <br /> <br />2990 S Bradford Pl Unit# F- <br />101118790 & 201824634/29/2024
